Technical Field
The invention belongs to the technical field of auxiliary equipment of microscopes, and particularly relates to an objective table levelness regulator with a height fine-adjustment function.
Background
Because of errors in the manufacturing and installation processes or a certain inclination angle on the surface of a sample, the posture of the sample to be measured generally needs to be adjusted when the sample is observed and measured by using a microscope, so that a better effect is obtained under a proper observation visual angle. However, the conventional swing sliding table can only realize angle adjustment in one degree of freedom, and thus two swing sliding tables are required to realize adjustment in two degrees of freedom, namely pitching and yawing. The adjusting frame of part of the equipment adopts a scheme that a steel ball and two threaded hand wheels are used as fulcrums to realize angle adjustment on two degrees of freedom of pitching and yawing. However, no matter which method is adopted, the distance between the objective lens and the sample is changed to a certain degree in the inclination angle adjusting process, so that the surface to be measured of the sample is out of focus, and the observation can be continued after the re-focusing is needed, so that the adjusting process is very complicated.
